“@GoldenMeth IMO $AEHR is a great long here and should hit its inflection point in the next few months like $AAOI. $AMKR better to wait next year since they’re in capex phase and their buildout comes online late 2027 or 2028 if I remember correctly. $FORM was a fan this yr” post →

2026-07-31Hmm, I personally added $AMKR in the $40's since I thought it was surprising it dropped that much after ER, even after $NVDA $1.5B deal + $TSM 10Y agreement. It's more of a 2028 name though, though they have separate ramps in 2027. - Did some cost averaging on names like Foci on drop to 400 (lea… · 326 likes · 66,496 views
2026-07-28T22:25:27I personally see it as extreme short term deleveraging that overshot many individual names. - $BE to $TER reported blowout results, with Bloom reporting 166% Y/Y rev growth + expanding margins + raised 2026 guidance... Teradyne reported 104% Y/Y revenue growth with 300%+ EPS growth. Your leading… · 2579 likes · 985,630 views
2026-07-13T00:45:13Just a semi recap TLDR: - $GLW glass bridge per Morgan Stanley has potential, but hard to displace FAU (like FOCI) in short term - $SPCX Starlink Gen 3 is scaling to 100,000 units (10x prev gen) creating possible capacity constraints for suppliers of switches to CCL. - PCB supply shortages are pr… · 2033 likes · 675,396 views

2026-02-24Year to Date: 412.72% Lot of it is just picking the right sector, profiting off of Jane Street algos weekly, and a bit of luck. In terms of bottleneck longs, these are currently my favorite: 1. Memory - Samsung, Sk Hynix, $SNDK, $MU, $SIMO 2. Photonics - $LITE, $COHR, $AAOI, $AXTI, (maybe Ya… · 3849 likes · 1,001,737 views

2026-01-19US Futures are down due to Greenland Tariff news. Many popular names on EU stock exchanges are now down: $ONDS (-8.55%) or $RKLB (-7.65%).

2025-12-05I've actually posted a breakdown + talked about each individual stock up there before if you follow what I normally post. This is just a consolidated list from history.
